>> mr. president, thank you for your time. >> translator: god bless you. wish you success. from cnn headquarters this is cnn weekend. we'll tell you who's behind the scandal. two dead and another green-on-blue attack in afghanistan just three days after joint patrols resume. as the number of coalition death rises so do concerns over the stability of the region. a vacuum of nothingness can be measured. how it's led to a groundbreaking discovery.

-- captions by vitac -- www.vitac.com it is sunday, september 30th. good morning, everyone. i'm gary tuchman in for randi kaye. wi start with battle between afghan soldiers and international troops. right now we know at least one coalition worker is dead. a civilian worker is dead as are a number of afghan troops. joining me on the phone is ben farmer, the afghan correspondent for the daily telegram. thanks for joining us and right now do we know how this clash started? >> reporter: no. they're only saying it's a suspected insider attack. the afghan officials have a little more information. they say there was a clash. there was an american soldier, afghan and two or three coalition soldrs killed.

it happened about an hour's drive southwest from the capital. it's an area where american troops are having a great difficulty securing the main highway in the country. now what caused that clash is not true, but investigators are on the way to the scene and they're trying to find out exactly what caused these deaths. >> now, ben, nato just resumed patrols with afghan. could this lead to another halt with that? >> reporter: well, i think it will be viewed with a lot of concern with coalition headquarters. you're quite right that around two weeks ago general john allen dramatically scaled back the number of operations of the number of americans and coalition forces staged with their afghan partners just to prevent just this sort of attack. those joint partnerships started to increase in the last few days, but now they'll have to decide whether -- what action they will take as a result of

these deaths. but first they'll have to final out exactly what happened. >> ben farmer from "the "daily telegraph."" we thank you very much for joining us. there have been about 50 of these so-called green-on-blue attacks, a fact that angers the top military commander there. here's what he told "60 minutes." >> you're in a tough spot right now. can you explain why the sudden increase in these attacks? >> i'm mad as hell about them, to be honest with you. we're going to get after this. it reverberates everywhere, across the united states. we're willing to sacrifice a lot for this campaign. wee not willing to be murdered for it. >> at a certain point if these attacks continue americans are going to say that's enough. >> it may be. it may be the voice right now that we're hearing. the key point us is for us to understand that the vast ma jart of the afghans -- and you've

lived with them. you understand these people -- they're with us on this. they understand right now the severity of this problem and the urgency of what's happening, and there have been afghans killed trying to save our forces when these attacks have been under way because that was the only reaction that they could have taken was to try to save us at the moment of that attack. >> regional coalition commanders in afghanistan have been given the go-ahead for the resumption of some of those patrols. those okays only came after review of their security situations. to politics now and more allegations of voter registration fraud in the sunshine state of florida. the complaints center around a company originally hire by the republican national committee. strategic allied counseling did registration drives. the new york times reporting

that the suspicious registration forms have now been found in ten florida counties. in colorado, one worker was caught on tape trying to register only mitt romney supporters. take a look. >> hi. >> i am polling people, but would you vote for romney or obama. >> wait. i thought you were registering voters a minute ago. >> okay. >> i am. >> who are you registered? all voters? >> i'm actually trying to register people for a particular party because we're out here in support of romney actually. >> and who's paying you for this? >> oh -- let me see. we're working for the county clerk's office. >> okay. you cannot come out here and register one party, lady. are you working for the county clerk's office? i've got it all on tape. you're working on the county clerk's office? >> i believe so yes. >> you're only registering

romney's people? >> we're trying to. >> and you're working for the county's office? what's your name. >> she said she was working for the county clerk's office but the county clerk said that's not true. he also said my office will not engage in partisan voter renl station, although he asked asking a preferential question before registering is not illegal now, cnn has not been able to confirm that, so what is the national republican committee saying about strategic actions? first of all, the party fired the company. this from ryan mahoney. we have zero tolerance. we have therefore cut ties with strategic allied consultants and urged the state parties to do the same. others followed suit and fired strategic. strategic allied consults is now being investigated by law

enforcement. it's quite a story. it's actually going be a little quiet for the next few days on the campaign trail. that's because they have something else to work on. here's senior political editor paul steinhauser. >> reporter: hey, good morning, gary. it's pretty obvious. one event will definitely dominate the white house. >> i'm looking forward to the debates r the first comes on wednesday night when they face off in denver. both candidates have a lot on the line, especially the gop challenger who a few days ago gave some insight into his debate preps. >> it's great to have senator rob portman. you know, he debates me now from time to time. he's playing barack obama in these mock debates we have. i don't like him very much anymore, all right? he keeps on beating me up and i keep going away shaking my head. >> reporter: he flies to colorado on monday night, hun r hunkering down while making final preparations.

then he goes to nevada and then goes behind closed doors before debate day. meanwhile both presidential campaigns play the expectations games, trying to lower the bar for their candidates. gary? >> paul, thank you very much. next hour we'll take a closer look at the art of the debate and the strategy of the dodge. we'll show you how dodging important questions can actually earn candidates points with voters. and a programming note, the first presidential debate of 2012 is this wednesday night. watch it live, 7:00 p.m. eastern on cnn and cnn.com. tomorrow morning the u.s. supreme court justices will formally kick off a new term. on the agenda, some of the toughest and most controversial issues of our day. here's joe johns with more. >> reporter: right after the supreme court health care's decision in june, chief justice john roberts joked to colleagues that he would find an island

fortress to escape the heat. here's how ruth termed the spring. >> it's been taxing. some have called it the term of the century. >> reporter: now three months later the court is back and there's no sign of it cooling down. >> the justices are moving right into the fire. they're tackling some of the most legal questions of the day. across the board probably the most biggest term in at least a decade. >> reporter: same-sex marriage, voting rights, and abortion are all likely to come up this term which kicks off monday. >> there are some very exciting cases already on the docket and there's a lot more in the pipeline that the court's going to be making a decision on soon. >> reporter: another set of big decisions will bring more scrutiny on the chiefs justice. rulings that the health care program he offered caused a rift

between anton and scalia. >> no, i did not have a falling out with justice roberts. >> loud words exchanged? slamming of doors? >> no? >> no, no. >> nothing like that? >> nothing like that. >> liberals fear a more hard line, dogmatic shift to the right. >> a lot of progressives are concerned that this might mean that chief justice roberts has built up some capital, some good will, and will now push the conservative agenda. >> reporter: tom goldstein who has argued before the court thinks roberts wants a more conservative court but h that he'll do it gradually. >> he's not trying to move the law radically quickly. i think justice scalia and thomas want to get to the end as quickly as possible and make the law conform to what they really understand, whereas the chief justice is more incrementalist. >> reporter: but conservative

court watcher doesn't believe that will change any time soon. >> certainly this is not a crusading conservative court until we have a shift in the membership of the court it's impossible to call it a court that leans more to the left or the right. >> reporter: for opinions that would be close, opinions will be paid attention to by justice anthony kennedy who's the swing vote. protests and bloodshed dominate international news. austerity measures continue to bring aim and outrage. we'll take you to madrid and the latest in protests over spap's latest plan for budget cuts there. in syria, the death toll and devastation continues to mount as fighting rages block by block in the country's biggest cities. we'll have the latest. americans believe they should be in charge of their own future.

cool segment. we're going to be talking about black holes. you've probably seen them in

popular sci-fi movies like "star trek," right? they're hard to find but hidden in space they're all over the universe. most galaxies, even our milky way, are full of black holes, and for the first time scientists have measured what's called the event horizon. i think of it as the point of no return for, well, everything. if you cross it, you will get sucked into an infinitely dense point in space. cause moll gist joins us now. he's an author of "a universe from nothing." lawrence, thanks for joining us. we appreciate it. >> it's good to be back. >> let's start out with what is exactly a black hole and how are they created? >> black holes is a creative name but basically they're a dense object. if i add a little bit more mass,

another tea spoon full of mass, you'll have to travel a little faster to the earth, a little bit more, a little bit faster and eventually if there's enough mass you'll have to travel the speed of light to leave earth. since nothing can travel faster than the speed of life. you're suck. as you shoot a laser beam up, it will go up and come back down. black hole is something where the escape velocity is greater than the speed of light and what goes in doesn't come back out. >> lawrence, how massive are they and how small can they be? >> that's the interesting thing about black holes. it's actually remarkable. they can be any size depending on their density. when i was a high school student i learned a fact that just amazes me and i want to tell you. the smaller the black hole, the denser it has to be. so say something the size of the sun, if it collapsed to the size of lauren where i am right now,

the entire mass collapsed to the size of london where a teaspoon would way a million tons or so, that would be a black hole. the average density of stuff if you piled it up together to be a black hole would only be the density of water because there's a lot more stuff there. and the neat thing is if you took our entire universe and asked what would its depsty have to be so we would be living inside a dense hole the density would only have to be twice. we could be living inside of a black hole. >> you learned all this stuff at m.i.t., right, lawrence? >> yes. >> okay. that's very impressive. so giant stars turned into black holes. what about 93 million miles away, our own sun? >> a last note. what happens, our sun is too small. it will basically just burn out with a women per rather than a

bang. when stars burn out they clachlts some collapse into a supernova. in one second the core of a star, the size of the earth, collapses to something the size of management in one second and forms one giant atomic nucleus, and that's so stiff that it bounces back and the star explodes. but if the star is still bigger, something like ten times the size of our sun, it's so massive that it doesn't stop anation. it's strong enough to counter even nuclear forces and the whole thing we high pocket size anyway will collapse into a black hole, and there are larger objects. at the core of every galaxy weekend see super mass holes and actually we don't yet know how they form. that's one of the reasons why we want to build the telescope and look at the earliest galaxies to see which came first like the chicken or the egg. >> do we have any idea roughly

how many black holes there are? >> no, not really except when we look at galaxies and there are a hundred billion or so, we tend to see large black holes at their centers. there are probably a lot of others that we can't see. of course, you can't see a black hole directly. the way you see a black hole is seeing stuff fall into it because, of course, the black hole doesn't shiechblt but when stuff falls into black holes they emit a lot of energy because they lose a lot of energy coming in. as a matter of fact a lot of the objects in the june verse, quasars, they have black holes in the center. they're really among the most observab observable. he's an author, lawrence krause. i can't say i understand it. either way, lawrence krause,

thanks for joining us today. we appreciate it. >> all right. it's always a pleasure. now to politics. a republican party caught in the scandal. a company hired by the go president obama may have illegally been registering voters. making up phony names. in next hour we'll tell you what else one of the workers is accused of doing.
